SAP Information Structures are used to store data for different applications like Materials Management, Sales, Purchasing or Finance. An Information Structure is a collection or group of information that is used for aggregation and evaluation of data. In this tutorial, we will discuss SAP MM info structure.

SAP MM info structure can also be created by using the transaction code MC21. For changing (editing) the info structure, we use the transaction code MC22 and for display of info structure we use the transaction code MC23.

We should provide a name for the new info structure – S845 with a description. The application we select is 02 – Purchasing, since we are dealing with materials management.

Create SAP MM Info Structure – Transaction MC21

The types of info structures include the following as seen on the screenshot below. We select Standard type of info structure for our example.
Info Structure Types

In the below screenshot, we can see the list of applications while creating the info structure. We select 02 – Purchasing for our case.
Application Entries List

Planning Possible Indicator tells that Flexible planning is possible in this info structure and can be supplied with planning data. We check this option in our case.

Once we enter the details, we can see the next screen wherein we have to select the Characteristics and the Key figures from the options as seen in the subsequent steps and the screenshot below.

SAP MM Info Structure – Characteristics and Key Figures

For selecting Characteristics, we select the Choose Characteristics option and for selecting the Key Figures, we select the Choose Key Figures option. Here, we get the selection list indicating the Fields on the Left Column and the Field Catalogs on the Right Column. We can select multiple tables and subsequently fields accordingly from those tables and combine different fields from various tables as per requirement.

In our example, we select Materials (Purchasing) Field catalog and select just Material and Plant as per our requirement. We can select as many fields as we want from the tables. Finally, we select Copy + Close option. A maximum of nine fields can be selected at a single time. We can combine more fields from different tables as per our requirement.

SAP MM Info Structure – Fields and Field Catalogs

We see the Fields which we have selected in the below screen and finally we have to press the Copy option and the Characteristics are displayed in the main SAP MM Info Structure creation screen as seen in the next screenshot.
Chosen Characteristics

We select the Fields for the Key Figures in the same way as we selected the characteristics earlier. For instance, in this case, we select fields Invoice quantity and Qty of goods received fields from Field Catalog Quantities (Purchasing).
Info Structure – Key Figures Field Selection

We finally see the fields selection for both Characteristics and Key Figures as done in the previous steps. For Characteristics, we have selected the following:

Material

Plant

For Key Figures, we have selected the following:

Purchase Orders

Invoice Quantity

Qty of Goods received

Info Structure Creation – Generate Table

Once this is done, we have to click the Generate button to generate SAP MM Info Structure S845. In the above screenshot, the Unit field indicates the unit of measure for the respective Key Figures. SID indicator indicates if the information is needed in the standard analysis. FID indicator indicates if the values of the Key Figure can be fixed for planning. We have to finally SAVE the Info structure.

As we know, the info structure consists of the characteristics, key figures and the period unit. We can create our own customized characteristics and key figures which can be used to create the info structure in the same way as we created in the above example.

We can select any fields from the source table and combine fields from different source tables. In the above example, we saw how we used the standard field catalogs for creation of info structure. We can also create our own customized field catalogs. Below we can see how we create the customized Characteristics and Key Figures data.

Maintain Field Catalogs

The path can be reached as seen in the screenshot and the path for the same is given below:

The same can also be reached using the transaction code MC18. For editing of Field catalog, we can use the transaction code MC19. For display of Field catalog, we can use the transaction code MC20.

In the below example for custom creation of characteristics, we use a new name ZNEW with description NEW-FIELD-CATALOG. We select the application as 02-Purchasing and select the catalog category as Characteristics Catalog as seen in the below screenshot.

Field Catalog Creation Screen – Transaction MC18

We click on Characteristics button as shown below.
Field Catalog Creation

We select Material Group Field from the Source Table Purchasing document item. We select fields Material Group, Material, Company Code.
Field Catalog Creation – Field Selection from Source TableChosen CharacteristicsField Catalog Finally Saved

Finally, we save our work and the Characteristics ZNEW is created by SAP system. Once we have created the Field catalog, we can look for it in the entries list and we can see the created field catalog is displayed here.
Field Catalog List

Maintain Key Figure Catalogs

Key figures are the numerical data that is shown according to Characteristics. Key figure is usually quantity or monetary value. In our example, we will create a new Key Figure KFNW with the description Key-Figure-New. The Catalog Category to be selected is Key Figure Catalog.
Key Figure Creation

Once this done, we have to click on Key Figures button.
Key Figures EntrySelection List

We can select fields from different tables as discussed earlier. Here, we have selected the fields as seen in the screenshot below.

We have to finally save the new key figure and it will be created by SAP.

With this we would like to conclude our tutorial on SAP MM Info Structures and related customizing.
